marattia การใช้

"Marattia " in the strict sense is found in the neotropics and Hawaii.
The two most prominent endemic floral species are " Marattia boivinii " ( kobila ) and " Blotella coursii " ( fanjana malemy ).
Formerly considered to be a much larger genus, genetic analysis has shown that " Marattia " in the broad sense was paraphyletic, and subsequently the genera " Ptisana " and " Eupodium " were split off.
However, " Eupodium " is distinctive among the Marattiaceae in only having one frond at a time ( occasionally two ), bearing awns along veins, and having stalked synangia, and one recent molecular phylogenetic study supported the recognition of " Eupodium " as a lineage distinct from " Marattia ".
